1.3.7 Safety
Our products normally become part of larger systems or installations. The information below is intended to
help you integrate the product into its environment without dangers to humans or material/equipment.
DANGER
Non-observance of the instruction manual
Measures for the prevention of dangerous faults or errors may be rendered ineffective or new
hazard sources created.
Thoroughly read the instruction manual
Take particular heed of the hazard warnings
Information
To achieve a high degree of conceptual safety in planning and installing an electronic controller,
it is essential to exactly follow the instructions given in the manual because wrong handling could
lead to rendering measures against dangers ineffective or to creating additional dangers.
Project Planning
24 VDC power supply: generate as electrically safely separated low voltage. Suitable devices
include split-winding transformers built in compliance with EN 61558-1/2.
Power breakdowns or power fades: the program structure is to ensure that a defined state at restart
excludes all dangerous states.
Emergency-off installations must comply with EN 60204 (VDE 0113). They must be operative at any
time.
Safety and precautions regulations for qualified applications have to be complied with.
Please pay particular attention to the notices of warning which, at relevant places, will make you
aware of possible sources of dangerous mistakes or faults.
Relevant standards and VDE regulations are to be complied with in every case.
Control elements are to be installed in such a way as to exclude unintended operation.
Lay control cables such that interference (inductive or capacitive) is excluded if this interference
could influence controller operation or its functionality.
Maintenance and Servicing
Precautions regulation BGV A3 to be observed when measuring or checking a controller after
power-up. This applies to section 8 (Admissible deviations when working on parts) in particular.
Repairs must be carried out by specially trained Schmersal staff only (usually in the main factory in
Wuppertal). Warranty expires in every other case.
Only use parts approved of by Schmersal. Only genuine Schmersal modules must be used in
modular controllers.
Modular systems: always plug or unplug modules in a power-down state. You may otherwise
damage the modules or (possibly not immediately recognisably!) inhibit their functionality.
Always dispose of (rechargeable) batteries as hazardous waste.

1.3.8 Electromagnetic Compatibility
Definition
Electromagnetic compatibility is the ability of a device to function satisfactorily in its electromagnetic
environment without itself causing any electromagnetic interference that would be intolerable to other
devices in this environment .
Of all known phenomena of electromagnetic noise, only a certain range occurs at the location of a given
device. These kinds of noise are specified in the applicable product standards.
The design and immunity to interference of programmable logic controllers are internationally governed by
standard
IEC 61131-2 which, in Europe, has been the basis for European Standard
EN 61131-2.
Information
Refer to IEC TR 61131-4, User's Guideline, for general installation instructions to be complied
with to ensure that hardware interface factors and the ensuing noise voltages are limited to
tolerable levels.
Interference Emission
Interfering emission of electromagnetic fields, HF
compliant to EN 55011, limiting value class A, Group 1
Information
If the controller is designed for use in residential areas, high-frequency emissions must comply
with limiting value class B as described in EN 55011.
Fitting the controller into earthed metal cabinets and installing filters in the supply lines may
produce a shielding compliant to the above standard.
General Notes on Installation
As component parts of machines, facilities and systems, electronic control systems must comply with valid
rules and regulations, depending on their field of application.
General requirements concerning the electrical equipment of machines and aiming at the safety of these
machines are contained in Part 1 of European Standard EN 60204 (corresponds to VDE 0113 part 1).
Electrical Immission Safeguard
To eliminate electromagnetic interference, connect the control system to the protective earth or functional
earth conductor. Practice best cable routing.
Cable Routing and Wiring
Keep power circuits separate from control circuits:
DC voltages 60 V ... 400 V
AC voltages 25 V ... 400 V
Joint laying of control circuits is allowed for:
shielded data signals
shielded analogue signals
unshielded digital I/O lines
unshielded DC voltages < 60 V
unshielded AC voltages < 25 V

Location of Installation
Ensure that temperatures, contaminations, impact, vibration or electromagnetic interference are no
impediment to the installation.
Temperature
Consider heat sources such as general heating of rooms, sunlight, heat accumulation in assembly rooms or
control cabinets.
Contamination
Use suitable casings to avoid possible negative influences due to humidity, corrosive gas, liquid or
conducting dust.
Impact and Vibration
Consider possible influences caused by motors, compressors, transfer lines, presses, ramming machines
and vehicles.
Electromagnetic Interference
Consider electromagnetic interference from various local sources: motors, switching devices, switching
thyristors, radio-controlled devices, welding equipment, arcing, switched-mode power supplies, converters /
inverters.
Particular Sources of Interference
Inductive Actuators
Switching off inductances (such as from relays, contactors, solenoids or switching magnets)
produces surge voltages. It is necessary to reduce these extra voltages to a minimum.
Throttling elements could be diodes, Z-diodes, varistors or RC elements. Their rating should
conform to the specifications provided by the manufacturer or supplier of the actuators.

2 Introduction
Cam control units are used wherever control actions should depend on a machine position. They are used in
machines running cyclically recurring processes.
A rotary encoder (in this case an incremental encoder) outputs the actual process values (axle position) to
the control unit which then controls the machine according to the current switch cam set up in the program.
Electronic cam control units are not only intended to replace mechanical program control mechanisms but
also designed to make their function more accurate, more generally applicable and more wear-resistant.
Operators benefit from the options of flexible manufacturing and shorter setup times. Latest electronic means
facilitate both operation and programming.
Conventional applications include:
Presses
Fillers
Glue application
Paper or foil feeding
Packaging machines
Figure 1: EFAS CAM Module
2.1 Working principle of cam control units
When developing the electronic cam control unit, we referred to the working principle of mechanical cam
control units in order to keep understanding the method of operation and programming simple.
2.1.1 From mechanical cam control units...
A mechanical cam control unit uses a section of a circular line to actuate a push-button. This section defines
as a "cam". Reasons of construction very much restrict the number of circular lines.
2.1.2 ...to electronic cam control units
In terms of electronic cam control units, the mechanical methodology translates as: every output is a circular
line. Thus, the number of parallel circular lines is equivalent to the number of outputs.
Programming a cam is therefore based on entering the tripping and releasing points of each section. The
section between a tripping and a releasing point turns the output on.

Version: 2018 / 02
2.1.3 Position detection
An incremental encoder picks up the current machine position.
Incremental encoders provide the angular momentum signals A and B.
Changes in position are identified by counting the momentum signals.
Checking the 180° offset of signals A and B allows you to establish the sense of rotation.
Since the absolute position is unknown when the system turns on, each incremental encoder needs to be
referenced. (Meaning that changes in position cannot recognised when the system is off.)
The absolute position is made known to the control unit by defining a home position which can be found
either by means of marker switches or by means of the incremental encoder's reference impulse (index).
2.1.4 Further benefits of electronics
A large number of cams with accurate trigger and release points can be programmed for every
output.
Once programmed, a cam can be easily changed or deleted.
If a new cam overlaps an existing one, both cams are joined to make up a single cam.
If a new cam is contained in a previous cam already, the new cam will be ignored.
Once programmed, a cam can be copied to other cam control units.
Physical dead times of actuators can be levelled out by the adjustable dead time compensation
feature.
Time cams enable the use of cams with constant times which solely depend on the triggering edge.
2.2 Programming
Programs can be created by various means, as appropriate. Use them to
create, test and optimise programs,
check them in online mode,
copy them within the same cam control unit,
copy them from one cam control unit to another,
save them.

3 Hardware
3.1 Mechanical design
The picture below illustrates the basic layout of the EFAS modules:
The housing mount consists of an aluminium profile with an integral snap-on device used to snap the module
to a 35mm DIN rail. The housing trough including the optical fibres for the status indicators, the side face and
the front is made of plastic and contains the module. The optical fibres for the signal state indicators (LEDs)
are located next to the spring-assisted combi plug. They slightly protrude from the housing and allow a clear
diagnosis at a glance.
Earthing
Connect the EFAS modules to earth by attaching the metal housing to functional earth.
Since the functional earth connector dissipates HF currents, it is of utmost importance for the module's noise
immunity.
HF interference is dissipated from the electronics board to the metal housing. The metal housing therefore
needs to be suitably connected to a functional earth connector.
You will normally have to ensure that
the connection between module housing and DIN rail conducts well,
the connection between DIN rail and switching cabinet conducts well,
the switching cabinet is safely connected to earth.

In special cases you may attach the earth wire straight to the module.
NOTE
Earth wires should be short and have a large surface (copper mesh). Refer to
https://de.wikipedia.org/wiki/ground_(electronics) or a similar source for further details
Installation
EFAS I/Os mount on 35 mm x 7.5 mm rails to DIN EN 50022.
Position
Mount with rail horizontally with the modules' multiple socket connectors pointing away from the wall. To
ensure that enough air gets in through the ventilation slots, leave at least 20 mm to the top and 35 mm to
adjacent devices or cabinet surfaces. Leave at least 20 mm of lateral distance to third-party units and cabinet
surfaces.

Order of Modules in Multi EFAS Systems
NOTE
In order to ensure that the entire EFAS system works properly, arrange the EFAS modules by
their specific E-bus load, placing the modules with the highest E-bus load immediately next to
the head module (bus coupler or controller). Take account of the head module's maximum bus
load.
To snap on a single module
Push up the module against the mounting rail from below,
allowing the metal spring to snap in between mounting rail and
mounting area as illustrated.
Push the top of the module against the mounting wall until it snaps in.
To interconnect two modules
After snapping on the first module to the rail, snap on the second module about 1cm away towards
the right of the first module.
Push the second module along the rail towards the first module until you hear the locking device
snap in.
To disconnect two modules
Push down the unlock button (see Figure5) of the module that you wish to disconnect from the
module to the left of it.
Push both module away from one another until they are about 1 cm apart.
To take down a single module
1. Push the module up and against the metal spring located
on the underside of the rail guide.
2. Tip the module away from the rail as shown in the illustration.
3. Pull the module down and out of the mounting rail.
